How convinced are you that human activities are a significant cause of changes to the Earth's climate and long-term weather patterns?

I'm very convinced about it. There's decades of evidence that supports and basically all of the scientific community is in agreement that we're a large part of the cause of the climate changing.

The issue is figuring out how to effectively mitigate and perhaps even reverse it somewhat in a way that is cost-effective and also realistically doable. Then getting everyone to agree to follow along with it.
